xgo does not find package, compilation fails #222

Closed kolaente closed 1 year ago

kolaente commented 1 year ago

I'm using xgo to build multi-arch docker images. Since recently, compiling my package fails because it can't find an internal package:

The package is present in the source tree, not sure why xgo is unable to find it. Is that a bug in xgo or did I misconfigure something?

CI run: https://drone.kolaente.de/vikunja/api/5356/5/3

It is reproducible, the package is open-source:

git clone https://kolaente.dev/vikunja/api.git
cd api
docker buildx build --platform linux/amd64 . -t api:test --load

(you need a recent version of docker with buildx available)

Looks like the "direct" run (still runs directly in the xgo docker container, but does not build a docker image) fails with a different error:

Seems unrelated to xgo?

Kind of embarrassing, but it looks like the package was cleared after generation and before building :man_facepalming:. Of course it could not be found.
